This review highlights critical gaps in polycyclic aromatic hydrocarbon (PAH) remediation research. It suggests expanding target compounds, using realistic contaminated materials, and implementing bioavailability measurements for effective soil and sediment cleanup.
Area of Science:
- Environmental Science
- Environmental Chemistry
- Soil Science
Background:
- Contaminated land poses significant economic and environmental burdens globally.
- Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants requiring effective remediation strategies.
- Thousands of studies exist, but current approaches may not fully address environmental challenges.
Purpose of the Study:
- To review and discuss three key scientific trends in polycyclic aromatic hydrocarbon (PAH) contaminated soil/sediment remediation.
- To identify limitations in current research and suggest improvements for future studies and management.
- To advocate for updated methodologies in PAH remediation research.
Main Methods:
- Bibliometric analysis of scientific literature on PAH remediation.
- Review of targeted compounds and experimental materials used in remediation studies.
- Discussion on the application of the ISO/TS 16751 bioavailability measurement protocol.
Main Results:
- The 16 US-EPA listed PAH compounds may be insufficient for current environmental concerns.
- There is a notable lack of remediation trials using co-contaminated or aged-contaminated soil/sediment.
- The systematic implementation of the ISO/TS 16751 protocol in remediation trials is underdeveloped.
Conclusions:
- Current PAH remediation research needs to broaden the scope of targeted compounds.
- Future studies should prioritize the use of more realistic, co-contaminated, and aged soil/sediment samples.
- Adoption of standardized bioavailability measurements is crucial for advancing PAH remediation effectiveness and management.
